Does vaginal reconstruction really work, and what does the doctor actually do?

Yes, in most cases. Vaginal reconstruction is usually employed to restore the vaginal anatomy that has been damaged as a result of vaginal deliveries. Many women eventually have significant symptomatic vaginal prolapse / pelvic relaxation as a result of the trauma of one or more vaginal deliveries. The surgical restoration virtually always results in improvement of the anatomy and function of the vagina.
